Class C Airspace Authorization for Drones in Canada (NAV CANADA Tool Guide)

Why You Need Authorization

Canadian Class C, D, and E airspace surrounds every controlled aerodrome — Pearson, YVR, Calgary, Ottawa, and dozens more. Under CARs Part IX, an Advanced RPAS pilot certificate is required to fly there, AND you need an explicit NAV CANADA authorization for the specific flight.

Flying without authorization in controlled airspace is a serious violation. Penalties include certificate suspension, fines up to $5,000 for individuals, and aircraft seizure.

The good news: NAV CANADA’s RPAS Flight Planning tool (sometimes called the “drone authorization tool”) makes the request process simple, often returning an authorization in minutes for routine requests.

Before You Start

You need:

• An Advanced RPAS pilot certificate (Basic does not allow controlled airspace operations)
• A registered drone (registration number on hand)
• A specific flight site with coordinates (lat/lon or address)
• Planned date, time, and duration
• Maximum altitude AGL
• Your pilot certificate number

Make sure you’ve completed your drone registration and have your Advanced certificate before submitting.

Step-by-Step: Using the NAV CANADA RPAS Flight Planning Tool

Step 1 — Access the tool Go to portal.navcanada.ca/rpas (you’ll need a NAV CANADA account — free to create).

Step 2 — Define your flight site Drop a pin on the map at your operating location, or enter coordinates / a postal address. The tool shows you what airspace classification covers the site and any nearby aerodromes.

Step 3 — Specify flight parameters

• Operating area shape (circle, polygon)
• Maximum altitude AGL (typically 100 ft or 400 ft)
• Date and time window
• Aircraft type and weight
• Pilot certificate number

Step 4 — Submit and wait For routine low-altitude requests in less-busy airspace, NAV CANADA’s automated system often returns approval in 5–15 minutes. Complex requests (higher altitude, near busy airports, longer duration) may take 24–48 hours and may require ATC review.

Step 5 — Receive the authorization You’ll get a digital authorization with conditions. Common conditions:

• Maximum altitude (e.g. “Do not exceed 100 ft AGL”)
• Time window (the flight must occur within the approved window)
• Coordination call (call the control tower 15 minutes before flight)
• Cancellation procedure if conditions change

Step 6 — Comply with the authorization Print or save a digital copy. Carry it during the flight. Follow ALL conditions — deviation can void the authorization and trigger enforcement.

Common Reasons Authorizations Get Denied

• Inside an aerodrome’s runway protection zone — too close to active runways
• TFRs (Temporary Flight Restrictions) active in your area
• Conflicting approved operations at the same time and location
• Insufficient lead time — submitting 5 minutes before flight may not get approved in time
• Pilot certificate not Advanced — Basic pilots cannot get controlled airspace authorization
• Drone over weight limit for the requested area

If denied, the tool typically suggests modifications (lower altitude, smaller area, different time window) that would be approvable.

How Long Authorizations Last

Single-flight authorizations are valid for the specific date/time you requested. Recurring authorization is available for ongoing operations at the same site — useful for inspection contractors, real estate photographers with regular client locations, or training operations. Recurring auth typically requires more documentation and ATC consultation.

Tips for Faster Approval

1. Submit at least 24 hours in advance when possible. Even routine requests can hit a manual review queue during busy periods.

2. Keep altitude requests modest. 100 ft AGL gets approved much faster than 400 ft AGL near busy airspace.

3. Avoid Class C airport runway final approach paths. Even legal-on-paper requests in these zones often get manually reviewed and may be denied.

4. Don’t submit overlapping requests. One request per planned operation. If conditions change, modify the existing request rather than submitting a new one.

5. Use clear operating area shapes. Tight, defined polygons are easier for ATC to approve than vague large circles.

What If You Need to Fly Last-Minute?

Same-day requests are possible but risky. NAV CANADA’s automated system handles many cases, but if your request hits a manual review queue, you may not have time. For commercial work that requires guaranteed authorization, plan 48+ hours ahead.

Tracking Multiple Authorizations

For commercial operators with frequent controlled-airspace work, tracking authorizations across multiple sites and flights gets complex fast. Tools like RPAS WILCO integrate the NAV CANADA airspace database directly into your site survey workflow — you can see authorization requirements before you even propose a flight to a client.
